I disagree. They made the right pick when they were on the clock (credit deserved), but they were quite often only in the position they were in due to luck in the lottery and luck with the picks made ahead of theirs (ie: Portland drafting Oden, Miami drafting Beasley and Memphis drafting Thabeet).
I do agree that they have done well with later picks. Just don't point at consecutive #2, #3 and #4 picks as purely good drafting. And don't point to the Raptors draft picks at #9, #13, #5 and #8 as comparison and justification for arguing that BC is a poor drafter; that's just not fair.
